ITEM-COUNTER FOR CALCULATING-MACHINES- Patented Auf. 25, 1914.

Application filed October 14,1912. Serial No. 725,592.

.To all wh om it' may concern,

Be it known that I, GLENN-J. BARN/rr, a

citizen of the United States. residing at Grand Rapids, hiliohigan, have invented certain new and nset'nl Improvements in Item- Counters for Calcnlating-Machines, of which' the following is a specilication.

My invention relates to iminoyements in item Counters for calculating 11iachine:-. and an object is to provide an item counter on any standard style of ealenlai machine by setting aside, as desired. ce1- tain recording dials and their actuating means for the purpose.

A further object is to provide means whereby a eonnter section may be thrown in 0r out of operative engagement Withont disturbing the readingI on said dials.

'Further objects, and objects pertaining to details and economies of construction and operation will definitely appear from the dctailed description to follow.

I accomplish the objects of my invention by the devices and means-described .in the. following specification.

The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred embodiment of my invention is clearly illnstrated in the accompanying drawin torming a part of this specification. in which t Figure I is a plan view of an adding' n1achine7 showing a portion broken away to eX- pose my device. Fig. II is a detail lett side elevation View of operating mechanism of an adding machine. Fig'. III is a sectional ele- Vation View of an adding machine showing' my improvement applied. taken on line 3-3 of Fig. I. Fin'. IV is an enlarged detail sectional View of the transfer part of an adding machine "with my imm'm'ement, taken on line 4-4 of Fig. V. Fig. V a detail soetional View taken on line 5*5 of Fig. IV. Fig'. VI is a detail rear view of thc trimiing' and stopping member of the transfer mechanism. Figi. VII is an enlarged detail fragter lever and eoiperating parts, 'withthe rclation oi certain parts shown by dottefd lines.

Similar ninnerals e? reference reifer to similar parts tl'ironghonl lthe several views,

and theJ sectional views are talien looking in 'the tlirertion nl the little arrows at the ends of the section lines. i

Considering' the numbered parts, I have shown my device adapted vto an adding inavchine of the t i je covered by mv Patent No.

9713.330 o1nr Nov. 22, 1910. rlhis is a key set, handle operated machine. In sach a machine, dial actuating rceiprocating` members advance a predetermined space and are forced hach to 'normal position during the operation ot'a crank or handle. The transl'cr ot the tens is effected in a machine oil this type hy storing` power against they tension of 'a spring. and providing means Whe-rehy when a dial ot' one denon'xination passes the carrying;r point, the dial next higher is driven by vii-lne of the pover stored asfatoresaid, an extra unit, thns recording the ten advanced troni thelmver dial. y

ln a mechanism of-this sort, each dial lends to rotate at each stroke of the handle one space morethan the number of spaces indicated by the depressed finger key corresponding to said dial. This is normally prevented by means of a. stop which limits the rotation of the dial to the nnmberoi" spaces yre])resented hy the'Cooperatingr depressed linger key. When the transfer point is reached on any. dial the rotation of this dial trips the stop cooperating with the dial of the next higher denomination and allows said dial to rotate one eXtra space. inechanimn is illnstrated and described in my latent No. 970.32%(3, dated November 22, i910, My present invention eoniprises mecha nism whereby this stop is thrown ont ofthe way so that at'eaeh movement of the handle the dial cooperating' with said stop will advance one space. It is not altogether new to provide mechanism whereby the normal stop for' any denomination is permanently thrown ont of Jihe Way. when at every movement of the handle its eo)mating` dial will register l l. This eonnts the handle strokes on this particular dial.

It ,is an object oi" my invention to overcome a diliicnlty in such a structure. If the counter be made operative when the machine is normal, one extra '1 will be registered on the counting dial by reason of throwing: ont the normal stop. n

The object of my present device is to merely position eertain parts by .suitable Allof this h switching means so that this stop is removed only as the handle is actually operated, and thus the item counter may be thrown in and out of operative engagement' without dis-A turbing the reading ot the counter dials.

ln Fig. Vl appears the carrying'parts. ln Fig. lV atrigger 1 is just about to contact with the pin 2 on the swinging member 3. See Fig. Vl. Extending from this movable member is an ear 5 whichc is the normal stop for the dial actuating reciprocating member d o1Lx the next higher denomination.

3, see Figs. 1V and Vil, is an upwardly projecting portion of the member 3. against which my device contacts during the operation of the handle.

Fig. I shows a plan vien7 of a calculating machine made according to my Patent No. 976,336, of Nov. 22, 1910, with my device added. 6 is the main operating shaft and 7 the operating handle. 8 is a sector on the left side of machine shown in Fig. H. le is a locking pitman having a reciprocating movement during the operation of the machine, as more fully described in my above mentioned patent. l

My invention may be applied to any member having a reciprocating movement in synchrony with the handle, but l ind it convenient in this instance, to coperate with the part 14. The connections back to the shaft 6 maybe traced through the connect ing parts 18, 12, 11, 10, 9 and.8, all of which are fully described in my said patent.

The keys and their connections and stops and the actuating handle, and the variousv means making up such a machine are here illustrated, but not particularly described.

The description is complete in my said former patent. l n

15 is a lever with an arm extending through a slot 14 in the link 1% During every movement of the handle 7, link i1 moves toward the rear ot the machine and the forward portion of its slot 14: contacts with the lever 15, causing the latter to swing on the vertical pivot 16 against the tension of the spring 17 provided to hold the same in normal positionu A support 21is provided for the lever 15 and pivot or fulorum 16 and is secured to the side of the case. At the other extremity of the lever 15 is the sliding member 18 adaptedv to slide under the shouldered rivet 20. One end of this slide 18 is bifurcated to guide it and keep its position on the lever 15. Extending from slide 18 is an ear 25 which is adapted to be -rec eived by the bifurcated end of 19 18 is a portion of 18 which adapted to strike 3 when in operative position at each movement of the handle; hence movement of the link lll. Extending through the keyboard of the machine is the item counter switch finger piece 22 and connecting parts to the switch 19.

i hey 23 is the pivotal po through plate of the machine.

Z2 is rigid with 19, and when 22 is moved to right or left 19 has a correspond` ing movement.

When the ringer piece is normal, as shown in Fig. l, 18 misses 3 during each handle movement. When the linger piece is moved to the left, then 18 falls behind 3, and whenv 1&1 strikes 15, 3 is forced toward the front of the machine, thus givingits coperating dial a transfer movement of one space. Thus it will be readily enden stood that a movement of 18 back and forth, actuated by 22 as described,"will in no way affect 3 assuming that the operating handle is in normal position, and that it is-the movement of this handle which trips the transfer stop.

This item counter switch and finger piece may be placed anywhere on the keyboard, but l have chosen to place it between the second and third column from the left, thus making the last two dials counters, which record every handle stroke.

Having thus described my invention, what l claim as new and desire to secure by Let ters Fatent is:
